Wordpress is plug and play on almost any webhost out there (some even have installers for it). Ghost is node.js which is barely supported by webhosting companies (you will most likely need a VPS or some specific node.js HaaS, at least). Will this not be a huge barrier to achieve the same traction Wordpress has?
